LaboratoryParathyrin.intact intraoperative percent change in Serum or Plasma
Definition
Primary hyperparathyroidism is treated by surgically removing one or multiple glands. The decision on what glands need to be removed is made based on PTH intact levels drawn during the surgical procedure. Differential sampling and intra-operative PTH values also help locate hard to find parathyroid glands. A decrease in PTH of 50% or more from baseline to post-surgery PTH predicts operative success.
